摘要
山东昌乐蓝宝石储量丰富，品位高，但由于铁含量高，吸收作用强，蓝宝石的颜色过深，透明度很低，需要进行优化处理。通过高温氧化处理，合理控制处理温度和处理气氛，可使蓝宝石的颜色变浅，透明度提高。
There are a lot of high-grade sapphire reserves In Changle Xian, Shandong Province. It needsto process because of its high iron content, intensive absorption action, too dark coIour and low transparen-cy. Optimum controlling the processing temperature and atmosphere can make sapphire with lighter colourand higher transparency.
